Powerful Accessibility Testing Features
AxeCheck provides a complete suite of automated accessibility testing tools that cover every aspect of WCAG 2.1 compliance, from visual design to assistive technology support.
Core Testing Capabilities
WCAG 2.1 AA/AAA Audit
Run a full audit against every WCAG 2.1 success criterion. AxeCheck tests Perceivable, Operable, Understandable, and Robust principles at Level A, AA, and AAA conformance.
- All 78 WCAG 2.1 success criteria covered
- Clear pass/fail results per criterion
- Severity-weighted scoring system
- Conformance level breakdown (A, AA, AAA)
Color Contrast Checker
Automatically analyzes every text element on your page against its background color. Flags combinations that fail the WCAG contrast ratio thresholds (4.5:1 for normal text, 3:1 for large text).
- Normal text (4.5:1) and large text (3:1) ratios
- Exact contrast ratio values reported
- Suggested accessible color alternatives
- Support for gradient and image backgrounds
Alt Text Validator
Scans every image, icon, and decorative element to verify proper alternative text. Detects missing alt attributes, empty alt on informative images, and generic placeholder alt text.
- Missing alt attribute detection
- Generic alt text warnings (e.g., "image", "photo")
- Decorative image validation (empty alt check)
- SVG and icon font accessibility checks
ARIA Role Checker
Validates that ARIA roles, states, and properties are used correctly. Catches common mistakes like invalid role values, missing required attributes, and conflicting role assignments.
- Valid ARIA role verification
- Required attribute presence checks
- Parent-child role relationship validation
- Redundant ARIA on semantic HTML detection
Keyboard Navigation Test
Verifies that every interactive element on your page is reachable and operable using only a keyboard. Identifies focus traps, missing focus indicators, and illogical tab order.
- Tab order sequence analysis
- Focus trap detection
- Focus indicator visibility checks
- Skip navigation link validation
Screen Reader Compatibility
Checks heading hierarchy, landmark regions, form labels, and semantic HTML structure to ensure optimal compatibility with screen readers like NVDA, JAWS, and VoiceOver.
- Heading hierarchy validation (H1-H6)
- ARIA landmark region coverage
- Form label association checks
- Live region and alert role verification
